Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] ARM: 2653/1: Fix memset and memzero macro double-reference of parameters Patch from Deepak Saxena The current memset() and memzero() macros on ARM reference the incoming parameters more than once and this can cause uninted side-effects. The issue was found while debugging SCTP protocol and with the specific usage of memzero(skb_put(skb,size),size). This call would call skb_put(skb,size) twice leading to badness. The fixed version copies the incoming parameters into local variables and uses those instead. Signed-off-by: Deepak Saxena Signed-off-by: Russell King
